The CD4512BM CD4512BC buffered 8-channel data selector is a complementary MOS (CMOS) circuit constructed with N- and P-channel enhancement mode transistors This data selector is primarily used as a digital signal multiplexer selecting 1 of 8 inputs and routing the signal to a TRISTATE output A high level at the Inhibit input forces a low level at the output A high level at the Output Enable (OE) input forces the output into the TRI-STATE condition Low levels at both the Inhibit and (OE) inputs allow normal operation
